The condition known as Multiple Personality Disorder (MPD) or Dissociative Identity Disorder (DID) is metaphysically strange. Can there really be several distinct persons operating in a single body? Our view is that DID sufferers are single persons with a severe mental disorder. In this paper we compare the phenomenology of dissociation between personality states in DID with certain delusional disorders. We argue both that the burden of proof must lie with those who defend the metaphysically extravagant Multiple Persons view and (...) that there is little theoretical motivation to yield to that view in light of the fact that the core symptoms of DID bear remarkable similarity to the symptoms of these other disorders where no such extravagance is ever seriously entertained.

According to a Kantian conception truthfulness is characterised as a requirement of respect for the agency of another. In lying we manipulate the other’s rational capacities to achieve ends we know or fear they may not share. This is paradigmatically a failure of respect. In this paper we argue that the importance of truthfulness also lies in significant part in the ways in which it supports our agential need to make sense of the world, other people, and ourselves. Since sense-making (...) is something we do together, and that we can support or undermine, it generates norms of interaction that constitute a further, distinct, mode of recognition and respect for another’s agency. But the requirements of truthfulness and support for sense-making sometimes conflict. Through a series of cases, we analyze why and when a rigid insistence on truthfulness is disrespectful of the other and undermining of their agency. (shrink)

We have argued elsewhere that moral responsibility over time depends in part upon the having of psychological connections which facilitate forms of self-control. In this chapter we explore the importance of mental time travel - our ordinary ability to mentally travel to temporal locations outside the present, involving both memory of our personal past and the ability to imagine ourselves in the future - to our agential capacities for planning and control. We suggest that in many individuals with dissociative disorders, (...) forms of amnesia, or other frontal lobe damage, our capacity for mental time travel is impaired, resulting in commensurate losses to agency autonomy, and a forensic condition essential for holding persons responsible: in legal terms, the capacity for mens rea.

Undercover marketing targets potential customers by concealing the commercial nature of an apparently social transaction. In a typical case an individual approaches a marketing target apparently to provide some information or advice about a product in a way that makes it seem like they are a fellow consumer. In another kind of case, a friend displays a product to you, and encourages its purchase, but fails to disclose their association with the marketing firm. We focus on this second type of (...) case and argue that the constitutive dispositions of friendship that provide for the development and maintenance of intimacy also render friends especially vulnerable to undercover marketing techniques and so to the exploitation of friendship for commercial ends. We show how this is corrupting both of the friendship and the commercial agent. (shrink)

What is the role and value of pleasure in addiction? Foddy and Savulescu have claimed that substance use is just pleasure-oriented behavior. They describe addiction as "strong appetites toward pleasure" and argue that addicts suffer in significant part because of strong social and moral disapproval of lives dominated by pleasure seeking. But such lives, they claim, can be autonomous and rational. The view they offer is largely in line with the choice model and opposed to a disease model of addiction. (...) Foddy and Savulescu are sceptical of self-reports that emphasize the ill effects of addiction such as loss of family and possessions, or that claim an absence of pleasure after tolerance sets in. Such reports they think are shaped by social stigma which makes available a limited set of socially approved addiction narratives. We will not question the claim that a life devoted to pleasure can be autonomously chosen. Nor do we question the claim that the social stigma attached to the use of certain drugs increases the harm suffered by the user. However our interviews with addicts reveal a genuinely ambivalent and complex relationship between addiction, value, and pleasure. Our subjects did not shy away from discussing pleasure and its role in use. But though they usually valued the pleasurable properties of substances, and this played that did not mean that they valued an addictive life. Our interviews distinguished changing attitudes towards drug related pleasures across the course of substance use, including diminishing pleasure from use over time and increasing resentment at the effects of substance use on other valued activities. In this paper we consider the implications of what drug users say about pleasure and value over the course of addiction for models of addiction. Well don't get me wrong, I love using mate. If I could use successfully I would. I'd still be using. I love using. I just don't like the shit that comes with it. (shrink)

Effective agency, according to contemporary Kantians, requires a unity of purpose both at a time, in order that we may eliminate conflict among our motives, and over time, because many of the things we do form part of longer-term projects and make sense only in the light of these projects and life plans. Call this the unity of agency thesis. This thesis can be regarded as a normative constraint on accounts of personal identity and indeed on accounts of what it (...) is to have the life of a person in the broad, rather than narrowly biological sense. It is also a fundamental condition of social life that persons within society fulfill a range of longitudinal roles: parenthood is one such obvious example, as are teachers, health professionals, engineers, artists, and many others. The fulfillment of these and other valuable social roles requires that agents have the capacity to rationally conceive of themselves as engaged in these roles and subject to the demands of them. To be unable to fulfill any such longitudinal social roles is to have a life deficient in value. The unity of agency is thus, we argue, something we rationally strive for, and something to be morally promoted. Psychiatric states that undermine the unity of agency are morally and rationally disvaluable. Using the example of dissociation, we explain how one such state may have this undermining or disruptive effect on the unity of agency. The therapeutic ends for psychiatry in conditions involving such states are thus seen more globally as the restoration of effective agency, that is, unified agency. (shrink)

Social persons routinely tell themselves and others richly elaborated autobiographical stories filled with details about deeds, plans, roles, motivations, values, and character. Saul, let us imagine, is someone who once sailed the world as a young adventurer, going from port to port and living a gypsy existence. In telling his new acquaintance, Jess, of his former exotic life, he shines a light on his present character and this may guide to some extent their interaction here and now. Perhaps Jess also (...) spent time at one of these port locations; perhaps their paths might even have crossed. They might be drawn into recounting some common events that indeed do establish a common link. Did they visit a certain famous landmark? Did they meet up at the same bars? And so on. When we open up to friends, acquaintances, colleagues, and close others through the stories we tell them, we do so by revealing bits of ourselves. (shrink)

Dissociative Identity Disorder (DID) (formerly known as Multiple Personality Disorder) is a condition in which a person appears to possess more than one personality, and sometimes very many. Some recent criminal cases involving defendants with DID have resulted in "not guilty" verdicts, though the defense is not always successful in this regard. Walter Sinnott-Armstrong and Stephen Behnke have argued that we should excuse DID sufferers from responsibility, only if at the time of the act the person was insane (typically delusional); (...) otherwise the presumption should be that persons with DID are indeed responsible for their actions. We find their interpretation of DID and of the way in which the requirements for criminal insanity relate to this condition worrying and likely to result in injustice to DID sufferers. Our thesis is that persons with DID cannot be responsible for their actions if the usual features of the condition are present. A person with DID is a single person in the grip of a very serious mental disorder. By focusing on the features of DID which have, as we argue, the effect of deluding the patient, we try to show that such a person is unable to fulfill the ordinary conditions of responsible agency (namely, autonomy and self-control).

Mary Walker (2012) argues that the narrative form that self-understanding must take is capable of providing a largely truthful picture of who we are, despite neuropsychological evidence suggesting the contrary. Walker describes three approaches to counter the conclusion of falsity in self narratives: that some truths are fully intelligible only within a narrative structure; that narratives contain non-factual content with a significance and meaning otherwise unavailable; thirdly, and importantly for our purposes, she offers a constraint ‘on what can count as (...) a correct or good self-narrative...to point to ways in which the process of self-narration should be connected to the facts’. In this commentary we elaborate and offer further support to Walker’s claim that ‘continual intersubjective checking’ provides a dynamic and corrective social mechanism for ensuring truth in self narratives.

Substance use and misuse occurs at a very high rate among people with mental health problems and the relationship between the two conditions is complex. In this paper we argue that treatment of substance use in dual diagnosis clients must begin from an understanding of the losses suffered by those with mental illness. We outline the fundamental condition of effective agency, unified agency, which is disrupted in mental illness and show how this is needed to secure access to central social (...) and moral goods such as continuing employment and satisfying relationships. We argue that drug use will be disvaluable primarily in so far as it too prevents access to this set of agential goods and focuses the agent on synchronic well-being to the exclusion of diachronic well-being. The goals and methods of treatment for dual diagnosis patients should thus reflect the primary impairment to unified agency. (shrink)

The decline in autobiographical memory function in people with Alzheimer’s dementia has been argued to cause a loss of self-identity. Prior research suggests that people perceive changes in moral traits and loss of memories with a “social-moral core” as most impactful to the maintenance of identity. However, such research has so far asked people to rate from a third-person perspective, considering the extent to which hypothetical others maintain their identity in the face of various impairments. In the current study, we (...) examined the impact of perspective, comparing first- and third-person perspectives, as well as memory type. This online study asked 201 participants to consider hypothetical scenarios in which either themselves or another person experienced different types of memory failures associated with a diagnosis of AD. For each scenario, participants rated the degree to which the depicted individual remained the same person, and how impactful the impairment was. Social semantic memory failures – involving failures to recognise a loved one – were rated as most detrimental to self-continuity, and procedural memory failures the least. Averaged across all memory types, people considered their own and their partner’s self-continuity to be more resilient to memory failures than that of a parent or stranger. However, this pattern was reversed for some memory types: forgetting semantic or episodic information about close relationships was rated as more detrimental from a first-person than third-person perspective. Our findings suggest that perspective and type of memory impairment interact to impact judgements about the extent to which people maintain their identity when they experience dementia, and highlight the importance of social relationships to maintaining a sense of self.
